PURPOSE:To perform correction processing with high efficiency without increasing its storage capacity by sectioning an input character string into (n)-character blocks when the input character string is not stored in a word dictionary, and referring to frequency information and substituting a character with a high evaluation value as a correct character. CONSTITUTION:A character string signal A inputted from a KANA (Japanese syllabary) keyboard 1 is passed through a character string converter 18 which converts special character concatenation into one special character to supply a signal B to a CPU12. A character string restoring device 19 restores a signal C to its original special KANA character string when the signal has a special character, and passes other signals as they are to a controller 4 as a signal D, which is sent as a signal E to the word dictionary to be looked up. A signal F when the word is stored in the dictionary 4 is sent to an output storage circuit as a signal G through a controller, and a signal N when not is outputted. The CPU12 when receiving the signal N sections the temporarily stored signal B into (n)-character blocks and sends them as a signal J to a frequency table 17 to obtain a frequency signal K; when a special character is contained, a special character freuqncy table 20 is looked up. The CPU12 calculates an evaluation value and substitutes a character with a maximum value as a correct character.
